7 Claims. 1

This invention relates to margin stop assemblies for typewriters.

An object of the present invention is the provision of a margin stop assembly which may be made as a unit and mounted on any type of typewriter.

Another object is the provision of an automatic margin stop assembly with which it is only necessary to release the margin stop and then move the typewriter carriage to the desired position in order to determine the size of the margin, after which the stop is locked in place.

A further object is the provision of an automatic margin stop assembly which is extremely simple in construction, which may be easily operated, and which is very unlikely to go out of working order.

This margin stop assembly may be constructed so that a margin may be set up at one side only of a sheet, usually the left side. However, it is preferable to construct it so that a margin may be set up at both sides of the sheet. A pair of parallel round locking rods are provided along with means for rotatably supporting them on and parallel with the carriage of a typewriter. Each of these rods is formed with a plurality of spaced aligned teeth radiating therefrom. At least one or, preferably, two margin stops are slidably mounted on the rods over the teeth thereof, said stops being adapted to be engaged by a carriage stop on the typewriter. Resilient means is provided for normally urging the margin stops towards each other. Means is provided on each margin stop for removably engaging the teeth of one of the rods to lock said stop thereon, each stop being engageable with a different rod than the other one. Each of the rods may be individually rotated to release the stop engaged therewith, and then rotated again to reengage the stop.

Other objects and features of the invention will appear from the accompanying description with reference to the drawings, in which:

Figure 1 is a plan view of the stop assembly,

Figure 2 is a front elevation thereof,

Figure 3 is an end view,

Figure 4 is a side view of one of the margin stops,

Figure 5 is a section taken on the line 55 of Figure 4,

Figure 6 is a side view of the other margin p,

Figure 7 is a perspective view of an alternative locking rod, and

Figure 8 is a side view of a margin stop for the rod of Figure 7.

Referring more particularly to the drawings, l0 diagrammatically illustrates the back portion of the frame of a typewriter, and II diagrammatically illustrates the carriage thereof, see Figure 1. A carriage stop l2 of the usual construction is mounted on the frame It at the back thereof substantially midway between the sides of the typewriter. This stop may be releasable in the usual manner.

A pair of round locking rods l5 and it are placed close to and parallel with each other. These rods may have any relationship to each other, but in this example of the invention, one is placed above the other. Suitable means is provided for rotatably supporting the rods on and parallel with the carriage ll of a typewriter. One way of doing this is by means of brackets I! located at the opposite ends of the rods and secured to the carriage in any convenient manner. All the ends of the rods I5 and [6 are mounted in the same manner, and, therefore, only one Will now be described in detail. Each end of each rod is provided with a reduced portion 20 rotatably mounted in a bushing 2| which is threaded into one of the brackets ll. A nut 22 looks the bushing in place in the bracket, while lock nuts 23 and 24 retain the reduced portion 20 in position. The nut 24 bears only lightly against the bracket I! so that the rod is free to turn in the bushing. An operating lever 21 is provided at one end of each rod, and suitable spring means may be provided for resiliently holding the rod in one position. A spring 26 may be provided for this purpose, one end of said spring being connected to a lever 21 and the opposite end anchored to the bracket IT, as at 29, see Figure 3. Stops 30 are provided for limiting the turning movement of the rod.

The rods I5 and I6 are provided with spaced aligned teeth 32 and 33. These teeth extend throughout the length of their respective rods and, in this form of the invention, are located on the tops of said rods.

Margin stops 35 and 3B are slidably mounted on the rods [5 and it. Each stop is provided with circular openings 31 and 38 which are just large enough to accommodate the rods I5 and I6, respectively. The opening 31 of stop 35 and the opening 38 of stop 36 are each provided with a slot 42 radiating therefrom and extending completely through the stop. One or more recesses 43 are formed in the stop and communicate with the slot 42. Each slot 42 is of a size sufficient to permit the teeth of the rod to move therethrough, whereas the recess or recesses 43 are located, at an angle to the slot 42 and are adapted to receive one or more of the rod teeth. With this arrangement, when a rod is turned so that its teeth register with the slot 42, the stop may be moved along the rod. On the other hand, when the rod is turned so that its teeth engage with the recess 43, the stop is locked on the rod. The springs 28 normally retain the rods with their teeth engaging therecesses it'oftwo stops.

The opening 38 of the stop'"35 and-'theppen ing 3'! of the stop 36 are each provided with a slot 36 radiating therefrom which is large enough to permit the teeth of a rod to moue-therethrough regardless of the setting of the rod.

it is always free of the other one.

whereas the stop 36 may be locked on the rod Iii;

Suitable resilient means is provided tornormally urging the stops 535 and 36 towards each means may consistent-a, spring, on elastic 3B which extends irom.--one-.stop to the-other, as clearly shcwn-in- Figure This sprling or elastic may be'supportedaonly,abyathe stops, as shown, or the. neutral portion thereof may/be anchored to one .or both' of then rods.

One of these, in this case the opening M1, is provided: with onexor more inwardly-projecting teeti'r'fit adapted to fit into the grooves 53 of the locking rod.

With this arrangement, the tooth or teeth :Bhnormally engage the teeth 51 of the locking rod so that the margin stop cannot move thereon.

Whenuthearodeiis rotated, the groove 53 moves one line with the tooth or teeth 62 so that the vstop .-may no.wmove along the rod. When the stop has reached the desired point, the rod is rotated to re-engage the margin stop thereon.
